Liquid crystal display panel

Abstract

Provided is a liquid crystal display panel, comprising an array substrate, a color filter substrate, and a liquid crystal layer disposed therebetween, wherein a photoelectric functional layer, which is arranged on a surface of the color filter substrate facing the liquid crystal layer or on a surface of the color filter substrate away from the liquid crystal layer, can influence polarization states of optical waves, and meanwhile generate electrical shielding effects. As such, the photoelectric functional layer, which has two functions, can serve as either a polarizer or an electrical shielding layer, thus simplifying a manufacturing procedure of the entire liquid crystal display panel.
